Bedtime. Just before lights out, oldest wrathling looks up, "there's a giant grasshopper on the ceiling". I say, "it is huge must be a female" and lift sharp eyed wrathling to catch and safely remove said giant grasshopper. Wrathling expertly pinches it, turns it over and says "spot on dad, it's a female and soon to be mummy grasshopper! Look the ovipositor is just about to come out and her belly is expanded with eggs." How can these little humans know such minute trivia about completely random things and yet be so completely uninterested in whatever happens in the school classroom?
